Topband: Light fiber question

[Shoppa, Tim]

I do not know of any analog optical coupling technology that has nearly the dynamic range of copper.

50dB is considered quite good HF dynamic range for completely sealed analog optocouplers. Start putting cables and junctions in there and it has to only get worse.

 Tim,
 Good information, but I was thinking of a way for "Mr. Average DXer" to get  a connection, that is not adding noise, from his on site receiving antenna.

I think that is called "a remote receiver connected by optical fiber
networking". Several folks use this technology on topband. Sometimes the
remote receiver is the other side of the world.

 I am now using twisted pair on my receiving Delta antenna and is less
 noise than the coax.

 Question: Any one ever tried using light fibers as a near ultimate
 transmission line from their receiving antennas?
